mariadb可以启用审计插件来对数据库的各种操作进行审计，以防运维背锅！
启用MariaDB的审计插件，并调整相关参数
MariaDB [(none)]> show variables like ‘%audit%‘; Empty set (0.02 sec)
安装MariaDB审计插件
MariaDB [(none)]> INSTALL PLUGIN server_audit SONAME ‘server_audit‘; Query OK, 0 rows affected (0.41 sec)
查看安装审计插件后的变量
MariaDB [(none)]> show variables like ‘%audit%‘; +-------------------------------+-----------------------+ | Variable_name | Value | +-------------------------------+-----------------------+ | server_audit_events | | | server_audit_excl_users | | | server_audit_file_path | server_audit.log | | server_audit_file_rotate_now | OFF | | server_audit_file_rotate_size | 1000000 | | server_audit_file_rotations | 9 | | server_audit_incl_users | | | server_audit_loc_info | | | server_audit_logging | OFF | | server_audit_mode | 0 | | server_audit_output_type | file | | server_audit_query_log_limit | 1024 | | server_audit_syslog_facility | LOG_USER | | server_audit_syslog_ident | mysql-server_auditing | | server_audit_syslog_info | | | server_audit_syslog_priority | LOG_INFO |
设置相关参数及说明：
1.设置记录的事件
MariaDB [(none)]> set global server_audit_events=‘connect,query,table‘; Query OK, 0 rows affected (0.00 sec)
注：connect,query,table可满足我们所有审计需求
相关事件说明可参考：https://mariadb.com/kb/en/mariadb/about-the-mariadb-audit-plugin/
2.指定不审计某些用户的操作
MariaDB [(none)]> set global server_audit_excl_users=‘liuwei‘; Query OK, 0 rows affected (0.01 sec)
3.审计日志存放的位置
server_audit_file_path | server_audit.log
4.设置日志轮转
MariaDB [(none)]> set global server_audit_file_rotate_now=on; Query OK, 0 rows affected (0.00 sec)
5.设置审计日志的大小
MariaDB [(none)]> set global server_audit_file_rotate_size=1024*1024*1024; Query OK, 0 rows affected (0.03 sec)
6.开启审计日志
MariaDB [(none)]> set global server_audit_logging=on; Query OK, 0 rows affected (0.00 sec)
7.设置日志可以轮转的个数
server_audit_file_rotations | 9
查看设置之后的参数：
MariaDB [(none)]> show variables like ‘%audit%‘; +-------------------------------+-----------------------+ | Variable_name | Value | +-------------------------------+-----------------------+ | server_audit_events | QUERY,TABLE | | server_audit_excl_users | liuwei | | server_audit_file_path | server_audit.log | | server_audit_file_rotate_now | OFF | | server_audit_file_rotate_size | 1073741824 | | server_audit_file_rotations | 9 | | server_audit_incl_users | | | server_audit_loc_info | | | server_audit_logging | ON | | server_audit_mode | 0 | | server_audit_output_type | file | | server_audit_query_log_limit | 1024 | | server_audit_syslog_facility | LOG_USER | | server_audit_syslog_ident | mysql-server_auditing | | server_audit_syslog_info | | | server_audit_syslog_priority | LOG_INFO | +-------------------------------+-----------------------+
查看审计日志是否进行记录：可以记录增删改查所有操作

在配置文件中配置审计参数，因为global重启后就失效：
[mysqld]
server_audit_events=‘CONNECT,QUERY,TABLE‘
server_audit_logging=on
server_audit_file_rotate_size=200000
server_audit_file_rotations=10
server_audit_excl_users=‘liuwei‘
重启生效
